TAMPING ATTACHMENT FOR CEMENT-BLOCK-MOLDING MACHINES.

To all whom it may concern Be it known that I, HENRY BAUTE, a citizen of the United States, and a resident of the city of Benton Harbor, county of Berrien, and State of Michigan, have invented certain new and useful Improvements in Tamping Attachments for Cement-Block- Molding Machines, of which the following is a specification.

My invention relates to improvements in tamping attachments for cement block molding machines and has for its object the provision of an attachment of this character which will be durable and economical in construction and which will be eflicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which- Figure 1 is a front elevation of a tamping attachment embodyin my invention, the same being shown app ied to a cement block molding machine which is shown in dotted lines, Fig. 2 is a vertical section taken on line a2m of Fig. 1 Fig. 3 is an enlarged detail sect-ion taken on line y-y of Fig. 2, and Fig. 1 is an enlarged detail section taken on line z-.2 of Fig. 1.

The preferred form of construction as illustrated in the drawings comprises a frame consisting of two substantially U- shaped members 1 which are spaced apart and connected by means of rods 2 and 3. The lower ends of the frame members 1 are adapted for connection with the frame or body 5 of a conventional cement block molding machine by means of securing bolts 41, said bolts passing through elongated slots 6 provided in the frame members 1 which slots permit of forward and rearward adjustment of the attachment relative to the molding machine in order to properly center the tampers over said molding machine as will be readily understood.

In order to adapt the attachment for-use in conjunction with molding machines of various widths, turn buckles 7 are interposed in the connecting rods 2 and 3 which evidently aflord longitudinal adjustment of said rods and hence lateral adjustment of the frame.

Specification of Letters Patent.

Application filed November 25, 1912.

Serial No. 733,393.

Arranged at the front sides of the frame members 1 are vertically disposed guide bars 8 the respective ends of which are securely fastened in said frame members 1 by means of set screws 9. Slidably mounted upon and extending between the guide bars 8 is a cross head comprising blocks or end mem bers 10 which slidably engage the bars 8, and two pairs of connecting bars 11 the respective ends of whichengage recesses 12 provided for the reception thereof in the opposite sides of the end members 10, as clearly shown in Fig. i. The bars 11 are releasably secured to the end members 10 by means of bolts 13, the arrangement being such that said end members will be adapted for lateral -or longitudinal adjustment relative to said bars upon retraction of bolts 13 in order to correspond with the lateral adjustment of the frame such as is secured through the employment of turn buckle 7 as before described. The snug fitting of the ends of bars 11 in recesses 12 however insure a rigid connection between the end members 10 which obviates the possibility of binding of said members upon the guide members 8.

Arranged between the pairs of spaced bars 11, as clearly shown in the several views, are members 14; adapted when in use to serve in the capacity of tamper carriers. The members 1 1 are provided in their opposite sides with recesses 15 for engagement by the bars 11, such construction evidently permitting of relative lateral adjustment of said members 11 between said bars but preventing relative vertical movement thereof. Said members are releasably secured in posit-ions of lateral adjustment by means of bolts 16 as will be readily understood. Each of the members 11 carries a vertically disposed stem 17 which passes centrally through the same as clearly shown in Fig. 8, said stems carr in the tam oers 18 at their lower ex-.

tremit-ies. Said stems are loosely mounted in the members 1d, the same being yieldingly held in positions of vertical adjustment by means of stops 19 adjust-ably secured upon said stems by set screws 20, and helical compression springs 21 which are interposed bet-ween said stops and the opposite sides of the members 14-. Provided upon opposite sides of the stops 19 are projecting cars 22 which slidably engage against opposite sides of-the carrier members 11 to serve as a means of preventing relative rotation of'the stems 17 and hence the t-ampers carried thereby. lVith the arrangement disclosed it will be seen that each of the tamper stems will be yieldingly held in operative position by a pair of counteracting springs which, when the device is in use, serve as cushions to absorb any shocks and jars which are incidental to the tamping operation. Further, with the arrangement disclosed it will be seen that lateral adjustment of the tampers permitted by simply retracting bolts or screws 16 in order to adapt the same to better serve the purpose for which the same are designed. Also by retraction of set screws 20, the tampers may be vertically adjusted as well as rotatably or angularly adjusted.

Manual operation of the cross head in order to secure vertical reciprocation of the tampers is secured through the medium of a manually operable oscillatory lever consisting of side members 23 which are fulcrumed at to links 25 the lower ends of which are pivoted 25 to the terminals of frame rods 2. Said side members 23 are pivotally connected at 23 with the end members 10 of the cross head. The forward and rearward ends of the members 23 are connected re spectively by means of cross bars 26 and 27, turn buckles 28 being interposed between the members 26 and 27 so as to permit of adjustment of said bars to correspond with lateral adjustment of the frame as is permitted through the employment of turn buckles 7 as before described. Helical compression springs 29 cooperate with said operating lever to normally hold the cross head and hence the tampers 18 at their up per terminals of movement, downward movement of the tampers being effected by grasping the bar or handle forming piece 26, as will be readily understood.

"While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:
